I believe I need to find bridge funding that will buy the property until the bank approval is done. 

That being said, did you actually have your credit run for a full approval?

I am waiting for my loan approval and the house is under pending.Later I noticed that there was no furnice filter in that house so I asked my buyer'agent to ask seller what size and type of filter they used for their furnace.

We told the guest we were unable to approve the booking because of this and called airbnb support- they said the account was under investigation and couldn't tell us anything further and they would eventually make a decision to block or allow the booking.

The HECM not will show as the total amount approved but not the total amount drawn.

My husband and I are starting our REI journey and have assembled a team in the area where we'd like to buy (not out-of-state, but 3 hours from where we live now where prices are more reasonable).We have a great lender, got approved, and are ready to buy.

I am worried about getting approved for a loan considering I have been working part time for the past couple years.

Was approved.

If so, are these difficult to apply/get approved for?

If you make $27k/yr, have a 650 score, you're approved for 100% financing?
